Storage protocols for the "seed seeking" era: BitTorrent

Speaking of BitTorrent, many people will find it strange. But when it comes to downloading "seeds," the term used to describe BitTorrent downloads, many of you will recall the days a few years ago when you were scouring the Internet for "seeds" to play games or watch movies. A seed file is an index file that records the location, size, address of the download server, and address of the publisher of the downloaded file.

To put it simply, BitTorrent is a peer-to-peer (P2P) download protocol that is far more efficient than traditional downloads from web servers. To give a vivid example, in school, the class gets together to copy an assignment, but only one student writes the assignment, and all the other students have to copy the answers. Each student copy homework speed is not the same, once more people want to copy homework, this process is difficult to carry out. So the common practice is that some students copy multiple choice questions, some students copy fill-in-the-blank questions, some students copy essay questions, and then we change to copy, the efficiency of a go up.

BitTorrent works like a copycat. Each user downloads only a portion of the file, and at the same time, our computer acts as a server to transfer that portion of the file to other users. This means that as we download, we are also uploading (what others have downloaded from our computers), so we are contributing by enjoying the download provided by others, so the more users download the file, the more seeds, and the faster the synchronization, the faster the download.

Pioneers of decentralized storage: IPFS

Despite the improvements, BitTorrent still has some problems, and to optimize these problems, IPFS has to be mentioned. I'm sure many readers are more familiar with IPFS, which is the basis for some of the most well-known decentralized storage projects such as Arweave and Filecoin. IPFS, which translates to interplanetary File System in Chinese, is a network transport protocol for distributed storage and file sharing.

BitTorrent downloads require the use of a seed file, and users need to put the location of all the downloaded content in the seed file to download. One of the significant advantages of IPFS is the use of a DAG data structure to store data. The advantage of this data structure is that IPFS stores and finds files in a content-based rather than address-based manner.

This means that if we're looking for a file, we don't need to know where it is, just what it contains. IPFS will be generated for each file a unique hash value (for example QmSNssW5a9S3KVRCYMemjsTByrNNrtXFnxNYLfmDr9Vaan), when the user needs to retrieve the file, you just need to ask IPFS who has this hash (QmS... Vaan) can complete the retrieval. Because hashes prevent duplicate storage, files with the same contents will not be duplicated by IPFS. This optimizes storage and improves network performance.

Dynamic storage solutions: Ceramic

From the above description, a careful reader may find that IPFS has a huge flaw. In IPFS, once a file is stored, it cannot be modified in the system because changing the file contents changes the hash value of the file, and the user cannot find the changed file through the original hash value.

This is a sore point with IPFS: it's not good at storing files that need to be updated. Therefore, there is an urgent need for an efficient and decentralized solution to store dynamic data. Thankfully, exploration of the track has already begun. Those of you who follow Web 3.0, SocialFi, or DID have heard of this project, Ceramic. Ceramic is a decentralized, open source platform for creating, hosting, and sharing data, and several DID and Social Graphs have been built on it. As mentioned earlier, IPFS does a good job of storing static files, but it lacks the computing and state management capabilities of its own to implement more advanced database-like features such as variability, version control, access control, and programmable logic. The emergence of Cermaic has solved the above problems to a certain extent.

Efficient version control

In Ceramic, each piece of stored information is represented as a superimposed log, called a Stream. Stream is similar to Git in concept. Git is an open source distributed version control system, which can effectively and quickly handle large and small project version management. It is the most popular version control software at present. It can be used to store code, track revision history, merge code changes, restore to earlier code versions and so on.

Git processes data like a "snapshot," a bit like sharing documents with Google Docs and viewing historical versions. Every time you submit an update or save the data state, it creates a snapshot of all the files at that time and saves the index of that snapshot. If the file has not been modified, Git does not re-store the file, but keeps only a link to the previously stored file, greatly increasing efficiency.

In fact, you can use Git to store dynamic data on IPFS as well. However, you need to create a hash-log file in Git to record the mapping table of every Git log and IPFS hash update, and you need to keep the synchronization dynamic manually, or use the IPNS naming system to keep the update dynamic. This operation is time-consuming and laborious, and the efficiency is very low.

Ceramic uses a "superimposed log" approach, and StreamID does not change in response to content changes, so it is very easy to store modified versions or go back to previous versions without constantly changing the hash value. Furthermore, Ceramic creates a new layer on top of other storage protocols, meaning that it is highly composable. Users can choose where to store their data, including decentralized Arweave, Filecoin, and centralized AWS, all of which can use Ceramic for automated version control. And because each Stream only stores logs and not data, Ceramic does not need a global ledger to synchronize data state globally, so Ceramic's horizontal scalability is very high.

Easy authentication and access control

In addition to the benefits of version control, Ceramic provides very convenient authentication and access control. When new data is to be added to the Stream, the modifier needs to authenticate, otherwise the data cannot be modified. Different streams can require different authentication mechanisms, and Ceramic provides a very powerful built-in authentication mechanism -- DID.

For example, 3ID diDs suitable for end users, key diDs suitable for developers, NFT diDs supporting authentication with NFT and Safe diDs suitable for DAO and other Safe diDs requiring multiple authentication ensure data security. At the same time, Ceramic gives the Stream programmable logic, such as Stream B can be accessed and upgraded if Stream A changes state. The appearance of Ceramic has greatly empowered the construction of Web 3.0. There have been many DID and Web3.0 social platform projects developed on Ceramic. Look out for CyberConnect, The Social Graph Middleware platform, Orbis for Web3.0 Twitter, The Convo Space, and more.

We look forward to the new possibilities that Ceramic infrastructure can bring to the application layer.
